A high-speed sluice assembly and method for transporting semiconductor devices includes a slide along which the semiconductor devices are transported and two independently controlled stoppers which control the transport of the semiconductor devices along the slide. Each of the independently controlled stoppers is connected to a separate actuator. Each of the actuators is also independently controlled. Several sensors are coupled to the slide to determine the position of the semiconductor devices as they are transported along the slide.
